Hoosfield Continuous Barley Long Term Trial, Rothamsted

Entry ID:
IACR.Hoosfield

Summary

Abstract:
This experiment began in 1852 at Rothamsted, England. The site was occupied (farmed?) since Roman times. Map of 1623 shows field in arable. Arable crops 1847-1851. Clay-with-flints overlying chalk; see Avery & Catt (1995) The Soil at Rothamsted.

Nearest meteorological station to the site: Rothamsted which is 1.2 km from the site at coordinates 0deg21minW, 51deg49minN Meteorological data is available from both a manual and an automatic station.

Variables measured are listed in the parameters section of this record.

This url links to the GCTE-SOMNET home page where additional project information and methodology can be obtained. This site is currently in a datasharing phase of the network where actual data will become available shortly, at different levels of accessibility. Please follow this link for more information.

Details of homogeneity of the plots: Some plots 6.7x5.3 m. Other sizes in earlier years. For many years cultivations were carried out both parallel and at right angles to the plots. As a result of soil transects carried out in the 1950s, cultivations were restricted and wide discards between plots introduced in the 1960s (Warren & Johnston, 1967).

b) Details of replication, randomization and controls

There are 0 replicates in the experiment. There are control plots described as follows:

There were two control plots until 1967. Since 1968 when plots were divided to receive different rates of N fertilizer all plots now receive N on acyclical system. All plots receive chalk - on a regular basis since the 1950s. All plots receive pesticides when necessary.
